Premise of the study: The study of infra-taxa has historically been considered the study of incipient species. Astragalus lentiginosus Douglas ex Hooker (Fabaceae) is the most taxonomically diverse species in the U. S. flora. To gain insight into the nature of infra-taxa, I ask whether an...
paleacea is its association with fungi in the Glomus group Ab. This is the same fungal group found with high specificity both in the sister species M. foliacea8, and forming intergenerational mycelial net- works12 between the haploid gametophyte and diploid sporophyte stages of the 'lower' ...
The Andean is the most species-rich region, but it is also the most densely populated. This region consists of three mountain ranges or cordilleras (Oriental, Central, and Occidental) that create multiple isolated inter-Andean valleys, each with large gradients of climatic conditions. The Andean ...
In a recent analysis13, we de novo-assembled 244 genomes of crAss-like bacteriophages from the human gut and classified them into 10 genus- and 4 subfamily-level taxonomic groups (Alphacrassvirinae,Betacrassvirinae,GammacrassvirinaeandDeltacrassvirinae) based on percentage of shared orthologous...
Framed rectangules correspond to extant species. Pale color used for hypothetical taxonomic units (HTUs, ancestral states). c. Principal component analysis based on the number of genes per each Pfam group that have been influenced by gene gain and loss in Trichoderma. Filled cicles correspond to...
Finally, the archaeal-specific GO term (“methylenetetrahydromethanopterin dehydrogenase activity”) is involved in folic acid biosynthesis and was first studied in the hyperthermophilic archaeal species Methanobacterium thermoautotrophicum [57]. We also note that the AE taxonomic group appeared soon after...

species world-wide. The most diverse subgenus inCortinariusisTelamoniaand its species have been considered one of the most taxonomically challenging in the Agaricales. Its high diversity combined with convergent, similar appearing taxa have earned it a reputation of being an impossible group to ...
The acI lineage of the phylum Actinobacteria is the most abundant bacterial group in most freshwater lakes. However, due to difficulties in laboratory cultivation, only two mixed cultures and some incomplete single-amplified or metagenome-derived genomes
carbon–biodiversity relationships dissipated at around 100 MgC ha–1, meaning that in less disturbed forests more carbon did not equal more biodiversity. Simulated carbon conservation schemes therefore failed to protect many species in the most species-rich forests. These biodiversity shortfalls ...
